ERWIN W. THOMPSON, 01? CHARLOTTE, NORTH CAROLINA.

METHOD FOR MANUFACTURING COTTON-BATTING AND PRODUCT OF THE SAME.

Specification of Letters Patent.

Application filed April 14, 1910. Serial No. 555,380.

To all whom it may concern:

Be it known that I, ERWIN W. THOMPSON, a citizen of the United States,residing at Charlotte, in the county of Mecklenbur and State of NorthCarolina, have invente certain new and useful Improvements in and forthe product of such method.

My object is to provide a simple and economical method for makingbatting and also to provide a new article of manufacture which will bemore desirable than the batting hitherto made, and especially the kindof batting used for domestic purposes, such as quilts, comforters orsimilar articles; and a further object is to produce an article whichmay be unrolled by the merchant and exhibited to customers, or ma bedispla ed in a show window with muc less liabi ity to injury' thananything that has heretofore been produced in this lme.

In order to accomplish these ends my invention, therefore, consists inthe peculiar ste s of the method and in the product more ful yhereinafter described, and then pointed out in the claims.

In the drawings I have represented one form of machine for erforming themethod and making the pro not.

In the accompanying drawings :-Figure 1 represents a front elevation ofmy invention, Fig. 2 a top or plan view, Fig. 3 a side elevation, Fig. 4a perspective detail view,

Figs. 5 and 6 views of details.

a The mechanism now to be described is desi ned rimarily to make acontinuous sheet of rein orced batting which may afterward be cut intovarious lengths and put up in packages, by rolling or folding, suitablefor presentation to the trade.

Figs. 1, 2 and 3 represent a series of three carding machines placedside-by-side in parallel arrangement. These machines are alike and hencea description of one will suffice for all.

Carded cotton or linters. are delivered from each machine simultaneouslyonto a short endless apron 7 which in turn delivers it to a camelback 5.The camelback 5 is of the well known type and may be actuated by anysuitable mechanism which it is not deemed necessary now to show. As thelinters are delivered from the carding machine onto the camelback theyform a web .61, which travels forward and is delivered off the free endof the camelback onto a lon carrying-0H apron 16, traveling in front 0'and common to allthree carding machines. The free end of the camelback1s equipped with the usual group of drawing-oft rollers 9 adapted toreciprocate back and forth on tracks 15 which constitute part of a table14. The apron 16 is stretched over idle rollers l 3 at the opposite endsof table 14, and is t1med to travel at a very slow speed relative to theback and forth movements ofthe camelback. The distance the carrying-01fapron 16 travels during a round trip of the camelback is represented bythe distance between the ends of lines 21 and 22.

25 indicatesa set of four drawing-oif rollers located at the left handof the series of the machines 1, 2 and 3, as seen in Fig. 1. Theserollers grip the three layers of batting and draw them all off the apron16 together.-

The drawing-01f mechanism may be so timed that the camelback will makeany desired number of folds, represented by lines 21 and 22, during agiven time. a

Web 62, which is produced by the middle machine 2, is reinforced andstrengthened by the means of a series of a'rallel threads or yarns 30which unwind rom a series of equidistant spools 26, and fall upon theweb. 27 is a standard on which the spools are supported. The spools aregiven the usual conical formation and each are passed through a threadleader 28. The threads 30 are not stitched in, but are allowed to restby gravity alone on the top of the cotton web 62 and are held in contacttherewith by means of a roller 29. This ressure roller 29 makes thethreads rip t o cotton sufficiently to draw them rom the spools with theweb gvhile it is carried forward over the camelack.

The threaded middle web 62 is deposited Patented Sept. 20, 1910.

in overlapping transverse folds on top of piece of quilting 33 of cottonbattin is'produced. This piece is carried forwar by the the stitchingpendentlyof each other.

36 is a table onto which the finished productis delivered.

In Fig. 5 is seen a modification wherein straight lines. 7

Summarizing the operation of the apparatus it may be said that thecarding machines 1, 2 and 3 are first filled with cotton andsimultaneously set in motion. Cotton issues therefrom in the form ofthin webs onto the short belts or aprons 7 whence they are transferredonto the camelbacks. The camelback of machine number 1 deposits the webback and forth transversely onto the longitudinal carrying-ofif-apron 16while the latter is traveling slowly beneath in a direction at rightangles to the path of the camelback.

In the act of depositin the web each camelback travels back and orthacross the apron 16 at a speed greatly in excess of the speed .of thelatter, trailing the webs with them.

This action forms the overlapping folds of each web. The web 61 from thefirst 'cardiriiig machine 1 lies directly on the carrying. o apron. Theweb 62 from second machine 2 lies on the first Web, and is carried alongby it. The web from all successive machines are likewise carried on topof the previous ones, so that these successive layers of webs are builtup on the carrying-olf-apron to make a final bolt of the requiredthickness.

All layers or plies are formed exactly alike, excepting the middle layer62' which is reinforced by the loosely laid threads 30 running crosswiseofthe length of the finished goods, and bound by the longitudinal seriesof stitches 31. This stitching gives a quilted formation and surface tothe goods, as shown more clearly in Fig.5, and when combined with theloosely spaced threads, produces an article'of manufacture whichpossesses greater strength, softness, and durability than anythinghitherto constructed for the purposes specified.

Quilt bats thus constructed may be unrolled by the merchant upon thecounter and exhibited to rospective customers, and may also be exhiited, with little damage, inv a show window, neither of which ispracticable with any other batting.

Another advanta e of my reinforced batting is that a quilt or comfortermay be 'madewith it, without the- "laboriou sprocess is made in zig-zag'instead of.

of quilting through and through, which usual with all other bats. Thisbat, being already quilted needs no further work to make it hold itsshape in the final quilt.

A further advantage of my construction is that a comforter or quiltcan'be removed from its case and cleaned and replaced, or a differentone substituted.

Although I have shown and described one form of my device it is evidentthat it couldbe varied in many ways that might naturally suggestthemselves to a skilled mechanic, without departing from the scope andspirit of the invention.

What I claim is 1. The method of making cotton batting and the like,which consists in forming a bottom or first web of battin secondly,forming a second or middle we of batting provided with a plurality oftransverse loosely laid strengthening threads; thirdly, covering thethreaded battin with a top or third layer of batting; and ourthly',stitching the whole, through and through to make a series of parallellines of stitching in longitudinal rows, to bind the transverse layersof loose threads into the fabric, thus completing a system ofreinforcing the batting, and giving it strength in both directions.

2. The herein described continuous method of making cotton batting andthe like of indefinite len rths, which consists informing a plurality ofwebs, incorporating into one of the webs during its process of formationcontinuous loose strengthening threads,

superposing the webs,. and then stitching them together alon lines whichcross the said strengthening t reads.

' 3. The method of making cotton batting and the like, which "consistsin first laying a plurality of 'loose artificial threads onto a web ofbatting; secondly, covering the threaded web with a top and. with abottom la er of batting, and thirdly stitchingthe w ole together.

4. A method of making cotton batting and the like, which consists offorming a bottom web, forming a middle web with loose strengthenincovering the threa ed web and then uniting the two webs by stitchingwith a top web of batting.

A new article of' manufacture for quilts,comforters, and the like, which comprises a layer or web of battingtransversely strengthened by continuous threads passing back and forthcrosswise of the layer or web and lines of stitching throu h the battingextending in; the direction 0 the length of the batting. q

6. A new ar icle of manufacture for quilts, comforters and the like,which comprises a layer or web of batting strengthened by continuousthreads incorporated into the web, such web being folded back and forthobliquely to the longitudinal line of the finished batting, anotherlayer of batting in superposed relation to the strengthened layer or weband longitudinal lines of stitching uniting the superposed layers.

8. A new 'article of manufacture consisting of a middle layer oftransverse loosely threaded batting incorporated between two layers ofuilthreaded plain batting and rows of longitudinal stitches through allthe layers.

9. As a new article of manufacture for quilts, comforters and the like,a cotton bat or sheet providedwith transverse loose con+ tinuousartificial threads, in combination with covering bats upon its oppositesides and rows of longitudinal equidistant stitches through all thebats.

In testimony whereof I aflix my signature in presence of two witnesses.
